TapeOp reviews the CC1
2010, February 4th
US magazin TapeOp, well known for its profound reviews, published a substantial test of the CC1. Two authors, Garrett Haines and Bob Katz independently performed extensive tests, including a blind listening test with 80 trials. They concluded "we should regard this listening test as very indicative that the Grimm clock makes the 192 I/O sound better." This is a very important conclusion, since it is the first time in history that there is scientific indication that jitter frequencies below 200 Hz do influence sound quality.

The Netherlands' main Hifi magazine 'Hifi Video Test' features a four page article about the CC1 in their February issue. Author Marnix Bosman presents background information on jitter and puts the CC1 to test as master clock for an Esoteric SA-10. He finds "a larger improvement even than I expected. The sound actually gains quality in all aspects." Using the CC1 as digital interlink reclock unit he enjoys improvements ranging from 'interesting' to 'massive'.

CC1 review in Music Emotion
2009, November
Dutch hifi magazine Music Emotion featured a review of the
CC1 by Jan de Jeu. On a test where the CC1 reclocks the spdif
line of his CD transport he writes: "... A beautiful
stereo image. Normally I never play this disc until the end
but this time I keep listening breathlessly. Amazed by the
difference I keep switching back and forth. (...) Both ends
of the spectrum are beautifully expressed in the sound of
the organ and brass instruments. The texture of the brass
instruments is fabulous."

British magazine Hi-fi World raved about the CC1 in their review for the May issue and granted it the maximum amount of 5 Globes, which is "Outstanding".

He enjoyed beautiful resonance and impact of hard struck piano chords. And he felt that the whole spectrum of the sound improved with the CC1. Please enjoy reading his full Hi-fi World review pdf.

CC1 review in Studio Magazin
2008, August
The editorial team of German magazin 'Studio Magazin' did two large articles on word clocks and were impressed by the CC1 and our support. From part 1 (August 2008): "The Grimm CC1 offers a beautiful and precise sound, a pleasure to listen to." From part 2 (September 2008): "The jitter measurement results of the CC1 were the best of all competitors" (compared to Apogee Big Ben and Mutec iClock)

Japanese publisher Ongen Publishing Co has given the CC1 their "Audio Excellence Award 2009" in the category 'Other Equipment'. Ongen publishes three Hifi magazines and a web-site. We are very honoured indeed!
The New York AES show was very successful. In particularly the CC1 attracted attention because nearly any studio can benefit greatly from its quality. To our big surprise the CC1 even received the "Pro Audio Review Excellence Award 2006".
At our first US AES show in 2004, Scott Dorsey of Positive Feedback gave the AD1 the 'Best new product in Show' award. Quoting: "Certainly one of the more carefully designed A/D converters I have seen in a while, and the simplicity of the DSD process makes it possible to implement with op-amps and comparators rather than relying on monolithic converter chips."
